Accupro 12183919 Ball End Mill 1 in 2 Flute Solid Carbide Altin

Product Description

The ACCUPRO 12183919 is a single-end ball end mill designed for profiling, contouring, and 3D milling operations in ferrous and non-ferrous materials. Built from micrograin solid carbide, it delivers the rigidity and edge retention required for demanding cutting applications. The tool carries an AlTiN (aluminum titanium nitride) coating that improves heat resistance and extends tool life at elevated cutting speeds. Key geometry includes a 2-flute configuration with a 40-degree helix angle and right-hand cut with right-hand flute direction. It is sized at 1 inch in cutting diameter with a 1.75 inch length of cut and a 4 inch overall length. Machinists and tool-and-die professionals specify this end mill for finish and semi-finish passes where accurate ball-nose geometry is critical.

This end mill suits CNC machining centers performing contour milling, cavity work, and die-and-mold profiling in shop environments ranging from job shops to production facilities. The 1 inch shank diameter is a standard size compatible with a wide range of collet chucks, end mill holders, and shrink-fit toolholders used in vertical and horizontal machining centers. The single-end design is the conventional choice for setups where tool runout and balance are carefully controlled. No extended-reach geometry is present, making this a standard-reach tool intended for accessible workpiece features.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• AlTiN coating for high-temperature resistance and extended tool life
• 40-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• 2-flute spiral flute design suited for profiling and 3D contouring passes
• Right-hand cut and right-hand flute direction for standard CNC spindle operation
• 1 inch shank diameter fits standard end mill holders and collet systems

Compatibility

Designed as an OEM-style solid carbide ball end mill fitting standard 1 inch bore end mill holders, collet chucks, and shrink-fit toolholders on CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following the machine tool builder guidelines for toolholder torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Verify minimum insertion depth in the holder to prevent pullout under cutting loads. Inspect the cutting edges and coating condition before each use; a chipped or worn edge should not be returned to service.
